Abstract

The utility model relates to a two-dimensional passive translational gravity unloading device of an air floating support, which belongs to the technical field of gravity simulation devices. The invention solves the problems of large frictional resistance and poor stability existing in the existing gravity unloading device. The counterweight type unloading mechanism includes a horizontal connecting frame, a chain transmission assembly and a sensor assembly, the middle part of the horizontal connecting frame is fixedly connected with the second air floating block, and the two sprockets in the chain driving assembly are respectively located on the two sides of the horizontal connecting frame. At the end, the two sprockets are connected by a chain, and the two ends of the chain are vertically arranged below the horizontal connecting frame, and the sensor assembly is fixed at one end of the chain, wherein the sensor assembly includes an angle sensor and is fixed at the angle For the tension sensor below the sensor, the object to be unloaded is fixed at the bottom of the tension sensor through a wire rope, and the counterweight is fixed at the other end of the chain. Through the combination of two-dimensional passive translation and vertical active compensation, the frictionless and smooth movement of the unloaded object in the two-dimensional plane is realized.

Description

technical field [0001] The invention relates to a ground simulation device for space weightlessness experiments, in particular to a two-dimensional passive translational gravity unloading device for an air buoyancy support, which belongs to the technical field of gravity simulation devices. Background technique [0002] Currently commonly used gravity unloading methods include: drop tower method, suspension method, water flotation method, air flotation method, etc. These methods have problems such as short duration, poor precision, resistance disturbance, high cost, and small range of motion, and cannot meet the requirements of high precision, large range, and smooth motion of the object to be unloaded in three-dimensional space. [0003] Patent 201210484568.6 provides a design method of a microgravity simulation system, which uses passive movement in two-dimensional space and active movement in the vertical direction. Because it moves in two-dimensional space in the form o...
